Glamour: Helen Mirren's style won praise and she was named as 'best dressed rack'

Unusual: Grayson Perry, left, made the final 25 but Kelly Brook was given the Best Undressed title

Other high profile female politicians named include Burmese pro-democracy leader Aung San Suu Kyi and Pakistani ambassador to the US Sherry Rehman.

Style Magazine editor Tiffanie Darke said: 'The diverse nature of this list demonstrates the importance of fashion in the overall conversation, confirming the role clothes play in creating a visual manifesto.

'What’s so encouraging is that among the
50 people celebrated, no two share a similar look; they all occupy a
different part of the fashion spectrum, using their own taste and
judgement to bring together an individual style that serves to inspire.'

Worst: Lady Gaga, a lover of unusual fashion, was named Worst Dressed by the panel of judges

Actresses Tilda Swinton, Charlotte Rampling and Helen Mirren also made the final 25, as did 'Clare', the alter-ago of artists Grayson Perry.

One of the youngest to be named on the list is six-year-old Shiloh Jolie Pitt, the daughter of Brad Pitt and Angelina Jolie, while at 86, the Queen is one of the oldest to feature on the list.

However, not everyone received a glowing report.

Kelly Brook, known for flaunting her famous curves, was named as the Best Undressed.

Lady Gaga - a lover of daring and outlandish taste - was given the Worst Dressed award.
